The Dinosaurs win a TV contest and travel to Mexico to collect their prize: a vacation in a tropical paradise. Unfortunately, they're in for a rude surprise when they discover the contest is a trap staged by the Raptors! The Raptors turn T-Bone, Stegz and Spike over to Dr. Becky Scarwell, and it's up to Bullzeye to rescue his friends from Roswell before they become guinea pigs in Scarwell's experiments.
